On 12 May 2014, exactly 650 years after its birth, the Jagiellonian University celebrated its Jubilee by honouring King Casimir the Great, its founder. A visionary monarch, he instilled the academic idea in Kraków, thereby making it one of the few ones that possessed a higher education institution.

As part of the official celebrations of the 650th Jubilee of the Jagiellonian University in Kraków, a commemorative plaque devoted to King Casimir the Great was embedded in the wall of Collegium Novum. The ceremony took place at noon. Prof. dr hab med. Wojciech Nowak, JU Rector, as well as Prof. Karol Musioł and Prof. Franciszek Ziejka, former JU Rectors, unveiled the plaque. The performance of the Jagiellonian University Academic Choir Camerata Jagellonica added splendour to the event.

Prof. Franciszek Ziejka, member of the Jubilee Committee, was the originator of the idea. The plaque was created by Prof. Jerzy Nowakowski from the Academy of Fine Arts in Kraków.
